To all whom it may concern:

Be it known that I, ALBERT Gnonc Koren- LIN. a citizen of the SwissRepublic, residing at- Steincn. in the Grand Duchy of Baden, Germany,have invented certain new and useful Improvements in AutomaticSpool-Changing Apparatus for Looms, of which the followinp is aspecification.

This invention relates to. automatic spool changing apparatus for looms,and it has .for its object to provide an improved removable spoolmagazine, having" guide fillet and transverse partitions which latterextend towardthe base of the magazine, of the kind adapted to hold alarge number of s cools, ted out singly by gravity, and to be filled inthe spinning mill or elsewhere for use in theweaving room, so that theweaver will be relieved of the labor of attending to the placing of thespools in the loom and as regards the renewal of his stock of spools hewill only have to see that the magazine when empty is replaced by a fullmagazine.-

The distinguishing feature consists in that the spools are conveyed fromthe magazine into the changing mechanism without any mechanicallyoperated movable appliances.

()ne construction of the improved magazinc is illustrated by way ofexample in the accompanying drawings in which Figure 1 is a verticallongitudinal section on the line O-D of Fig. 3, Fig. 2 is a. verticalcross section on the line A-B of Fig. 1, and Fig. 3 is a plan of so muchof an automatic spool changing apparatus as is necessary to illustratethe invention a is a'rectangular box open at the top, havingsides andbottom all at right angles to one another and a clear inside width onlyvery slightly greater than the length of a spool. Its other dimensionsare preferably such as to enable it to hold as many spools as will allowof convenience in handling the box. One end wall of the box is formedwith a spool outlet opening extending the entireinside width of the boxadapted to be closed by a slide 6. In the box are a number of transversepartitions c 0 whose pur pose is hereinafter described.

d are side plates between which a feeder e of known construction (thatmay be rotary as shown, or fixed) is mounted and is provided with arms 1which are inclined downward toward the feeder and serve to receive andsupport the magazine acting as brackets extending rearwardly, from theoutlet 'opening of the magazine supported, under and along the basethereot' so to hold the entire magazine tilted downward toward itsfront. The arms f may be extended and adapted to receive a secondmagazine, so

that as soon asthe first magazine is empty, the second full magazine canbe moved forward into its place, this work being conveniently done byboys appointed for this purpose. Suitably arranged ledges and stops areprovided for determining and sccuring the correct position of themagazine that is in use at the time.

When the slide 6 is drawn up, the spools are caused by their weight andthe inclination of the magazine to roll out unimpeded through. theopening in that end of the box. Each .spool as it issues from the box,is guided at its ends by guide fillets g which are provided on the sideplates (1. and isthereby caused to pass unimpeded directly to the feedere which conveys the spools in the usual. manner to a point where theyare acted upon by the inserting hammer m of the spool-changingapparatus.

The transverse par-tit ons c and (2 have the function of relieving thelower rows of spools of some of the superincumbent weight. of the upperrows, which would otherwise prevent the lower spools from movingforward. The partitions are spaced to provide room between each twopartitions for superimposed rows of filled spools and are eachvertically inclined and extend down toward the base, so as to leave apermanently free passage for two or more filled spools, ex-

cepting the last inclined partition, before the outlet opening, whichonly leaves a permanently free passage for one filled spool.

The transverse partition 0 which as indicated extends down almost to thelowest row of spools has also more particularly the function of causingthe foremost spools to pass in turn and with complete freedom out of thebox and into the guides g. The lower guide fillets are formed on bothsides with an opening closed by a spring-pressed flap the thread andwhich still contain'more or 105. h. Any spools which have beenejected-from I the loom shuttle on account of breakage of" series ofadvancing spools so that they may enterthe feeder' eaglain. It would notbe the other spools. A guide fillet 2' provided on the bottom of thebox, is arranged to keep the lowermost spools in position by azine, of adepth Slightly greater than the i along the bottom of the ma azine.-with' able cap the magazine may be closing said outlet opening,-titi'ons spaced to provide room between each gage in the engaging inthe groove formed by the foot is of the spool tube and the weft fillingZ;

The magazine may be filled in the spinhing mill, where the spools aretaken from the spinning machine and placed directly into the magazine,provided that the free .end of the threadhas been already wound on thenose of the spool tube or on a detachmounted thereon for thepurpose ofenabling it tobedrawn ofi' subsequently by automatic means. of thethread is separated after the spool has been removed from the spinningmachine, filled in any other place. 1

What I claim is 1. A removable spool magazine of rectangular open-toppedbox shape, with sides and bottoms all at right angles to one another,and of an internal 'width very slightly greater than the length of aspool, a spool outlet opening in its front end I ing the whole internalwidth of the maggreatest diameter of'a filled spool, means for twopartitions for superimposed rows of filled spools and each verticallyinclined and extending down'toward the base so as to leave a permanentlyfree passage for one filled spool, and aguide filletfshaped to engrooveformed by the foot and the yarn filling of the spool, along the bottomofthe magazine, as set forth.

2. In automatic spool changing apparatus for looms, the combination of aremovable spool magazine of rectangular open-topped box-shape with sidesand f bottoms all at right angles to one another, and of an internalwidth vervslightly greater than the length of a spool, a spooloutletopening in its'front'end wall extending the 'whole internal widthof the magaz ne, of a depth slightly greater than the greatest diameterof afilled spool, means for closing said outlet opening, transversepartitions spaced to between each two partitions provide room offilledx-spools and for superimposed rows each vertically inclined .andextending:

a guide fillet along the bottom of the magazine, with a feeder andguides between the magazine and said feeder, whereby the spools passingout unimpeded from .the-
